After the electrons pass through the parallel plates in Problem 54, they pass between another set of parallel plates [(B) in Fig. 16.35]. These plates also have an area of 2.50 cm by 2.50 cm and are separated by a distance of 0.50 cm.

(a) In what direction must the field be oriented so that the electrons are deflected vertically upward?
(b) If we neglect the gravitational force, how strong must the field be between these plates in order for the electrons to be deflected by 2.0 mm?
(c) How much less will the electrons be deflected if we do include the gravitational force?
